Add an object to many containers?

Hi, I'm new with C3 and C2. I'm making a space shooting game and get a problem. When destroying enemies, they drop power-up items. These items have many types with different sprites (I've already put them in a family) but have the same effect (2 glowing dots rotating around, which is also a sprite) behind. I'd like to use container to group the effect sprite to each one of item sprite, but it's impossible. The effect sprite can be in only one container. Are there any way to deal with this? Manually creating and destroying the effect sprite is somehow inconvenient.

You can't add an object to multiple containers. But you can create a simple event that will attach the effect sprite to each item:

On ItemsFamily created -> ItemsFamily spawn EffectSprite
                          EffectSprite pin to ItemsFamily[/code:2vkq1xm7]

And another event to destroy it:
[code:2vkq1xm7]On ItemsFamily destroyed 
   System -> Pick EffectSprite by comparison EffectSprite.Pin.PinnedUID=ItemsFamily.UID   -> EffectSprite destroy
[/code:2vkq1xm7]

Thank you, sir! It's worked!
